Goodyear Eagle F1 tyres
Last year I changed over to Goodyear Eagle F1 tyres and have found them to perform well in all weather conditions, including a 3,800 mile blast to southern Spain and back in the space of 10 days.
I have read various comparisons between OEM SO2's and F1's on this board and a common remark is the difference in the sidewall strength, which I agree is dramatically softer on the F1. Up until now I had assumed that this would make little practical difference once the tyres are inflated.
However, a recent incident appears to highlight a weakness in the F1:
Early on a dark and very rainy morning near my home, I was forced by an oncoming vehicle to reverse about 30 metres along a single track road. As usual it was hard to see backwards and my two near-side wheels glanced the kerbstones, which were of normal height and in good condition. My speed was no more than 2 mph.
Once the oncoming vehicle passed I drove on up the hill. After 1/2 a mile or so the steering started tugging to the left and I stopped to investigate.
Both near-side tyres were flat!
There was no visible damage to the tyres and no marks on the wheel rims. I initially thought that the slight contact with the kerb must have broken the seal and caused the deflation.
I hitched a lift with the wife and took the 2 offending wheels for a check-up at the local ATS garage, where it was discovered that each tyre had a small puncture in the sidewall and were beyond repair.
It suggests that the relatively weak F1 sidewalls may be particularly susceptible to such contact, so be aware.

Interesting.........and worrying.
The new F1 D3's (not available in s2k sizes yet) have the non-deflating technology - or "run-flat" i think it may be called - maybe maintaining a stonger tyre in this situation??

What psi were you using on the F1's?

When I had Eagle F1s on my mk2 Golf 16V I wrecked one immediately (on the way home) in a pothole, didn't hit the pothole particularly hard but the tyre was instantly flat.
GoodYear replaced it free of charge.
Oh and tyres were absolutely amazing, they must be pretty soft rubber because the whole set lasted under 15000 miles and they were swapped front to back at 7000ish.
Could be worth writing to Goodyear, it worked for me.

A stiff sidewall on a tyre doesn't mean that it will be more resistant to puncture, we are talking about two different property's, Rigidity(stiff side wall) and resistance to penetration, these elements are not necessarily related.
